A friend of mine is putting a plug gap of 45 thousands on a big block chevwith a vertex mag. I used to have a joe Hunt mag 35 years ago and thought I gapped plugs at half that or less. If the gap is 45 , does it do any damage to parts, hurt mag , Etc. -----Jimmy D.
I am new to mags, just bought a bbf ronco mag, I love it , but still expermenting.On the Vertex web site it says gap the plugs .018 to .045.I would kike to know what would be an optium setting.521 STROKER, ALUM. HEADS.He said the dist. was locked out at 0 deg. does that sound right?
